    Effect of Addition of Locally Available Carbohydrate Sources on Nutritional Value of Ensiled Mixture of Apple Pomace and Wheat Straw
    (CSK HPKV, Palampur, 2023-01-16) Raj, V M Gowtham; Rani, Daisy
    Limited availability of quality feeds is a major constraint behind low livestock productivity among small holder farmers in the Himalayan region. This study was conducted with the aim to find out some suitable locally available carbohydrate source for ensiling and thus improving the nutritional worth of apple pomace (AP) and wheat straw (WS) (85:15) silage. Molasses, maize flour, wheat flour, rice flour and jaggery, were used and their amounts were calculated by considering their nitrogen free extract (NFE) contents, i.e., all the carbohydrate sources supplied the same amount of readily fermentable carbohydrates as provided by 4 percent molasses. AP and WS (85:15) was ensiled along with urea (4%), soya bean meal (4%) and respective carbohydrate materials, in laboratory anaerobic culture jars for 28 days. From the results obtained from proximate principles, cell and cell wall contents and fermentation parameters the total score was calculated on the basis of number of times each treatment appeared on rank 1. Ensiled mixtures containing molasses, wheat flour, jaggery, maize flour and rice flour as carbohydrate sources were ranked as 1,2,3,4 and 5 respectively on the basis of in vitro studies. On the basis of in vitro studies silage of mixture containing AP, WS, molasses, urea and soya bean meal was compared with that of silage prepared by using AP and WS (without any additives), in five (per group) gaddi goats of average body weight 11.53 and 11.57 kg, respectively, for nutrient utilization. Dry matter intake (g/kg W0.75), gain in weight, apparent digestibilities of nutrients (DM, NFE, NDF, ADF and cellulose), TDN, TDN intake and nutritive ratio in goats fed ensiled mixture of AP and WS were significantly higher compared to that of goats fed silage of mixture containing AP, WS, molasses, urea and soya bean meal. The goats in both the treatments were in positive nitrogen balance. It was concluded that, there was no added advantage of mixing carbohydrate source, urea and soya bean meal in making silage of AP and WS in goat feeding.
